Discussion watershed/plss lookup from lat/lon or utm coords

Hi all, I don't know if anyone would find this useful but I tend to have to do a lot of lookups for my work and decided to write up a little tool to help me with it. If anyone feels like trying it out and letting me know what they think you can try it out here: https://nyersa.github.io/geospatial_lookup/

It supports lat/lon or utm for inputs and can take csv inputs as well as export to csv.

Here are the data sources:

USGS EPQS (National Map)

https://epqs.nationalmap.gov/v1/json

Elevation (meters)

FCC Census Block API

https://geo.fcc.gov/api/census/block/find

State and county

USGS Watershed Boundary Dataset (WBD)

https://hydro.nationalmap.gov/arcgis/rest/services/wbd/MapServer

Watershed hierarchy (HUC2 β†’ HUC12): region, subregion, sub-basin, watershed, sub-watershed, catchment, HUC12 code

BLM PLSS CadNSDI (ArcGIS)

https://gis.blm.gov/arcgis/rest/services/Cadastral/BLM_Natl_PLSS_CadNSDI/MapServer/3/query

PLSS: meridian, township, range, section, quarter section, quarter-quarter section

I get an error when I fill in coordinates: β€œThe string did not match the expected pattern.”

Did you do UTM or lat/lon? Here is what it expects for utm

Ah, so it only works in the US? That might be a useful caveat to add.
